Description

Fuzzy control has been applied to many kinds of real industrial processes. In the design of complex systems such as multi-input/multi-output systems and nonlinear systems, it is difficult to acquire expert control knowledge and to determine optimal parameters of membership functions. This paper presents a simplified design method for fuzzy servo systems for nonlinear plants. The features of this method are as follows. (1) This method consists of a simple design procedure. (2) This method guarantees stability of fuzzy servo systems. (3) This method results in the rejection of steady-state error and disturbance. Finally, the effectiveness of this design method is verified by a simulation experiment of control of the water level of a multi tank system.
